Application filed December 15, 1899. Serial No. 740,419. (No model.)

To all whom it may concern:

Be it known that I, FRANCIS L. COOK, a citizen of the United States of America, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Stoppers for Bottles, of which the following is a full, clear, and exact description.

This invention relates to improvements in stoppers for bottles of the class which are made of wood and constructed hollow and thereby rendered flexible, whereby it is enabled to conform to the opening in the neck of the bottle to fill the same while under a [5 degree of compression and exerting a yielding force relatively thereto.

The objects of the invention are to render a stopper impervious to moisture and to the air in a manner which is inexpensive and without deteriorating the flexibility of the stopper, and to construct a hollow two-part wooden stopper with the plug portion thereof hollow in a novel way, whereby the opening within the stopper is entirely closed and whereby the stopper is strong and durable, the same having a comparatively large or wide head or top which will notbe readily broken or severed from the plug portion of the stopper in the withdrawal of the same from the bottle.

The invention consists in a stopper for a bot: tle substantially as hereinafter described,and set forth in the claims.

Reference is to be had to the accompanying 3 5 drawings, illustrating my improved stoppers,

in which- Figure l is a central vertical sectional view through the stopper, which is shown as in its position within the neck-opening of a bottle.

0 Figs. 2, 3, and 4 are central sectional views through my novel two-part stoppers in which prevails a similarity, with, however, slight structural modifications.

In the drawings, A represents the body or 5 plug portion of the stopper, having therewithin the opening or chamber Ct. As shown in Fig. 1, the said opening is formed leading from the upper end of the stopper downwardly to near the lower end of the plug portion. Suficient thickness of wall is left between the inner chamber and the external surface for all necessary stability, and yet the thickness of the wall is not so great as to render the stopper inflexible, but it is, on the other hand, conformable to the opening within the bottle-neck.

In Fig. 2 the plug portion A and the head portion B are constructed separately. The said plug portion is in the form of a thimble or frustum of a cone, with its lower end closed and its upper end open. The head portion B is constructed of a greater diameter than the widest part of the plug portion and has in its lower end or bottom the annular groove d, into which the upper annular portion f of the wooden plug-shell is fitted, the parts being permanently and effectually united by glue or other adhesive.

Fig. 3 is substantially like Fig. 2, with the difference that in the bottom of the top B a circular depression or recess 01 is provided, into which the upper end of the thimble-like plug-shell is fitted, its external inclosed surface being secured by glue to the margin of the depression 01 while its end also receives connection by glue with the top wall of the chamber into which it is set.

In the stopper shown in Fig 4: the head 13 is constructed comparatively wider, with the circular depression 01 within its under side, and the thimble-like plug-shell A has the external flange g at its top, the same entering the circular opening in the bottom of the stopper-top. These parts are united by glue, and a layerof packing his interposed between 8 5 the top wall of the stopper-top and the flangetop of the stopper-plug, the same extending entirely across the top of the opening a within the plug.

These constructions of hollow two-part stopo pers are such that I may produce closures for bottles having an external aspect very much the same as that of a solid stopper, and yet, with all desired flexibility and conformability, substantial unrecessed tops are pro- 5 vided which will not be stripped or separated from the plugs in withdrawing the stoppers from the neck-openings of bottles in which they are closely fitted.

Having thus described my invention, what :00

I claim, and desire to secure by Letters Patent, is-

1. A stopper for a bottle having the plug portion thereof constructed in the form of a hollow thirnble or shell, of Wood, and having! rzat its bottom, and having its upper annular portion entered and secured by glue within said groovein the head, substantially as do.- scribed.

3. A stopper for a bottle having the plug portion thereof constructed in the form of a hollow wooden thimblc closed at its lower end andopen at its" upper, end; andyhaving the head portion thereof separately=formedand constructed with a circular opening in its under side within which the upper end portion of the stopper-plugis fitted and glued, and 1 the layer of packing; hplacedin saidcircular opening inthe head next above the .upper end of the plug, the same-"extending across the top opening Within the latter, substantially as described;

Signed by me at Springfield, Massachusetts, this 9th day of December, 1899.

FRANCIS L. COOK.
